  • Author: WAFA LI

Ingredients

Scale
  • 12 oz (340g) rotini pasta
  • 2 cups cooked, shredded or cubed chicken
  • 3 cups broccoli florets, chopped small
  • 2 tbsp unsalted butter
  • 2 garlic cloves, minced
  • 1½ cups heavy cream or half-and-half
  • 1½ cups shredded mozzarella cheese
  • ½ cup grated Parmesan cheese
  • ¼ tsp ground nutmeg (optional but classic)
  • Salt & black pepper to taste
  • Optional: pinch of red pepper flakes, 2 tbsp cream cheese for extra silkiness

For topping:

  • ¼ cup panko breadcrumbs
  • 1 tbsp melted butter
  • Extra Parmesan

Instructions

  1. Prep: Preheat oven to 375°F (190°C). Grease a 9×13″ baking dish.
  2. Cook pasta & broccoli: Boil rotini until just under al dente (about 1 minute less than package directions). In the last 2 minutes, add broccoli to blanch. Drain and set aside.
  3. Make sauce: In a large skillet, melt butter over medium heat. Add garlic; cook 30 sec. Pour in heavy cream; bring to a gentle simmer.
    Stir in mozzarella, Parmesan, nutmeg, salt, and pepper until melted and smooth. For extra richness, add cream cheese now.
  4. Combine: In a large bowl, mix cooked pasta, broccoli, chicken, and sauce until well coated.
  5. Assemble: Transfer to baking dish.
  6. Add topping: Mix panko, melted butter, and extra Parmesan; sprinkle evenly over top.
  7. Bake 20–25 minutes, until bubbly and topping is golden.
  8. Rest 5 minutes before serving.
💡 Make ahead: Assemble unbaked casserole up to 1 day ahead. Cover and refrigerate; add 5–10 min to bake time.
